This article discusses four ways to make a Docker container appear on a local network.

In the same way, a container’s hostname defaults to be the container’s ID in Docker. You can override the hostname using --hostname.

Use host networking. If you use the host network mode for a container, that container’s network stack is not isolated from the Docker host (the container shares the host’s networking namespace), and the container does not get its own IP-address allocated.
